Can't use parameters from one email template in another

I'm trying to edit the emergency number called email alert to include the extension name but I'm getting "Parameter %%EXTFIRSTNAME%% does not exist" error. I copied it directly from another email prompt, so it's not misspelled. What's the deal?

I've run into this same issue. The default email template for emergency number dialed only includes the extension number. It would be very helpful to include the name of the extension in the email as well.

Is there a variable that can be included in the template so that the extension name is displayed?

Regarding email templates in general: Is there a list of which variables may be used in each type of email template? I found this link: http://www.3cx.com/blog/docs/customizing-email-templates/ which indicates that a list of variables is displayed on the right hand side of the screen when editing email templates, but I don't see it on my screen (3CX version 14 with SP3).

Up until V14 SP2 there used to be a side bar with all the parameters listed, however all available parameters in each email template have since been included in the default templates so it kind of felt redundant.
